Genes affected
CHDH (HGNC:24288): (choline dehydrogenase) The protein encoded by this gene is a choline dehydrogenase that localizes to the mitochondrion. Variations in this gene can affect susceptibility to choline deficiency. A few transcript variants have been found for this gene, but the full-length nature of only one has been characterized to date. [provided by RefSeq, Dec 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.1672G>A (p.A558T) alteration is located in exon 9 (coding exon 7) of the CHDH gene. This alteration results from a G to A substitution at nucleotide position 1672, causing the alanine (A) at amino acid position 558 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
